Here's a solution that uses the Arrow module:

def wait_until(specified_dt: arrow.Arrow) -> None:
"""Stay in a loop until the specified date and time."""
# Initially check every 10 seconds.
refresh = 10
current_dt = arrow.utcnow()

while current_dt < specified_dt:
    # Check every millisecond if close to the specified time.
    current_dt = arrow.utcnow()
    if (specified_dt - current_dt).seconds < 11:
        refresh = .001

    time.sleep(refresh)
